Our first set of spectacles in the 19th Century room could well be in the wrong room! This style could date back as far ago as 1780. However, these are much more likely to be early 1800s”
The temples, which are the side arms of the spectacles, extend so that they could be tied with a ribbon behind the head or tucked under the wig. Temples themselves weren’t invented until the 1700s, before that spectacles were just balanced on the nose!
As the 19th Century progressed, things didn't really change much. The loops on the ends of the temples got smaller.
Towards the end of the 19th Century spectacles began to be about style, as this pair of tortoiseshell spectacles with their decorated case show.
